No. because the PSP costs more. But you can probably trade A Sony PSP for a Nitendo DSi. =] yes actually you can you just need extra money
The DS Lite has sold a lot more than the PSP overall, but it's a matter of what you want, the PSP has much better graphics and controls, but the DS has 2 screens, a touchscreen and is cheaper.
The psp has allot more things to do than the ds lite and more hacking abuility.
Yes you can trade a DSi for a DS Lite at Gamestop.
